Proxymetry3 - 4

The sub-title of today's post is: "On the origin and evolution of ghost-water" (a type of nomad water).

There are two types of nomad water.

One type is water which the scientific community commentariat sees, the other type is the ghost-water hidden right before their eyes, yes, the water hidden in very plain sight.

Some people can't "see" the ghost-water, some can, which brings up the old saying "there are none more blind than those who refuse to see."

Today, then, I will again point out the ghost-water that has been hiding in our eyes for quite some time, and then point out some 5th grade physics that can remove every mystery about ghost-water (except maybe the spookiness of not having discovered it earlier).

The twin nomad of ghost-water (ice sheet melt-water) is commonly seen by many, and is added to their sea level change (SLC) calculations.

The major quantities of ghost-water, however, are not added to their SLC calculations.

Some scientists know about it, but the majority of those in the crowd who write about SLC seem to always miss it.

They do not add it onto their mathematical calculations concerning SLC, whether or not that SLC is in the form of sea level fall (SLF) or sea level rise (SLR).

Today, as I wrote above, I will differentiate between these twins, ghost-water and the other twin, the water everyone can see already (only if they want to).

II. The Visible Twin

The long and short of it is covered by this quote:

"In fact, melting ice from Antarctica and Greenland (map) is giving the oceans huge infusions of water, which then gets pulled toward the Equator — counteracting a millennia-old slimming trend around the planet's middle, experts say."

(National Geographic, emphasis added). That twin adds to the bulge at the equator, or as we call it, SLC.

That bulge is 42.72 kilometers in magnitude.

The emphasis added to the following quotes alludes to those bulge events which take place at the Earth's mid-section:

"An equatorial bulge is a difference between the equatorial and polar diameters of a planet, due to the centrifugal force of its rotation. A rotating body tends to form an oblate spheroid rather than a sphere. The Earth has an equatorial bulge of 42.77 km (26.58 mi): that is, its diameter measured across the equatorial plane (12,756.27 km (7,926.38 mi)) is 42.77 km more than that measured between the poles (12,713.56 km (7,899.84 mi)). An observer standing at sea level on either pole, therefore, is 21.36 km closer to Earth's centrepoint than if standing at sea level on the equator. The value of Earth's radius may be approximated by the average of these radii." - Wikipedia
"Beginning in the 16th century, humanity’s understanding of our world and the cosmos was revolutionized as we became aware of a simple fact. The Earth moved! Not only did it move about the Sun, but it also rotates. And while it would take several centuries before this became universally accepted (aka. a few people had to endure persecution and house arrest) the fact that the Earth rotates about our Sun and on its axis soon became accepted fact.In fact, the rotation of our planet on its axis and around the Sun are the cause of just about every stellar phenomenon we humans have come to take for granted." - Universe Today
"The Earth has an equatorial bulge of 42.72 km (26.5 miles) due to its rotation. That is, its diameter measured across the equatorial plane (12756.28 km, 7,927 miles) is 42.72 km more than that measured between the poles (12713.56 km, 7,900 miles)." - Mr. Wizard

Twins have similar genes but nothing indicates they have to be identical in all cases (Scientific American).

It is the same with the twins I am talking about.

The twin that is known by some as: "melting ice from Antarctica and Greenland (map) is giving the oceans huge infusions of water, which then gets pulled toward the Equator" (Section II above) is substantially "genetically" the same as its ghost-water twin.

IOW, after the ice melts to make the "visible" twin, they are both water at that moment, they both then flow away from the coastal area of origin, they both flow toward the equator, and both of them are moved toward the equator by the forces of the Earth's rotation (Fig. 4).

But the ghost-water is neither ice, ice-sheet calved ice-bergs, nor melt-water; no, it is seawater that existed there a long time while its twin was still ice (Note: only an amount of ghost-water "equal" to the ice sheet's gravity loss escapes).

Ghost-water is seawater drawn up, like a perpetual high tide, against the coastline of land masses that have ice sheets on them.

It is drawn there and then held there by the gravitational power of the ice sheet's mass (see Mitrovica video below).

As the ice sheet melts, the cumulative power of that ice sheet's gravity decreases, releasing some of the ghost-water twin along with the other twin, the ice sheet's melt-water.

They are both then relocated toward the equatorial bulge, according to the laws of the forces of gravity, as well as those caused by the Earth's rotation.

V. The History of Ghost-Water's Twin

A scientist in 1888 wrote about it:

To our knowledge, Woodward (1888) was the first to demonstrate that the rapid melting of an ice sheet would lead to a geographically variable sea level change. Woodward (1888) assumed a rigid, non-rotating Earth, and therefore self-gravitation of the surface load was the only contributor to the predicted departure from a geographically uniform (i.e. eustatic) sea level rise. This departure was large and counter-intuitive. Specifically, sea level was predicted to fall within ∼2000 km of a melting ice sheet, and to rise with progressively higher amplitude at greater distances. The physics governing this redistribution is straightforward.
